I put it in about 6 months ago and am very happy with it. I especially like that both the voltage and current charge/discharge rate are displayed and can be checked just by glancing at it without having to push any buttons (though I would have preferred minus sign in front of the amperage value to indicate when it is discharging as the visual difference between the words "CHARGE" and "DISCHARGE" on the display isn't very much due largely to the smallish font and my old eyes).

Be sure to get the Compact version as the name is a misnomer. The easy to read display is quite a bit larger than the Victron Energy battery monitor it replaced. I also tested the both the amperage and voltage readings, comparing them with what a multimeter showed and they were spot on.

I've no idea how accurate the % indicator is as I never look at that. I learned the hard way not to trust what battery monitors tell me with regard to that.

For the record, I've had the Link 10, Link 20 and Victron Energy battery monitors on the boats I've owned and I like this one the best.
